Abstract

Objective: To determine if differences in respiratory muscle strength could explain any posture related effects on oxygenation in convalescent neonates. Methods: Infants were examined in three postures: supine, supine with head up tilt of 45degrees, and prone. A subsequent study was performed to determine the influence of head position in the supine posture. In each posture/head position oxygen saturation (SaO(2)) was determined and respiratory muscle strength assessed by measurement of the maximum inspiratory pressure (PIMAX). Patients: Twenty infants, median gestational age 34.5 weeks (range 25-43), and 10 infants, median gestational age 33 weeks (range 30-36) were entered into the first and second study respectively. Results: Oxygenation was higher in the prone and supine with 45degrees head up tilt postures than in the supine posture (p
